A super PAC supporting Sen. David Vitter (R-La.) — and potentially his 2015 candidacy for governor — will announce later this month that it raised $1.5 million in 2013.

The total was first reported by the Baton Rouge Advocate and confirmed by lawyer and GOP fundraiser Charlies Spies, who is leading the effort.

Here's more from the Advocate:

The dollars raised by The Fund for Louisiana’s Future could help fuel a re-election bid or a run for governor, depending on what Vitter, R-La., decides to do. By drawing in seven digits during 2013, the fund now is in a million-dollar club that includes Ready for Hillary, the Super PAC aiming to get former Secretary of State Hillary Clinton into the next presidential race.

“We've had very strong support for the senator and his agenda,” Spies said from Washington, D.C.

By the end of this month, The Fund for Louisiana’s Future will report raising $1.5 million in 2013, with more than 70 percent of the contributions coming from Louisiana residents and businesses. Fundraisers were held inside and outside Louisiana. Vitter attended some of the fundraisers as a special guest.

Spies next week will appear in front of a Louisiana ethics board to ask that the super PAC be allowed to accept contributions in excess of $100,000 — the state limit for individual contributions.

Vitter has said he will decide soon whether to run for governor. Gov. Bobby Jindal (R) is term-limited in 2015. Vitter would be up for reelection to his Senate seat in 2016.
